American Civil War of 1861-1865

The American Civil War was a conflict between the Union (the North) and the Confederacy (the South) that lasted from April 12, 1861, to May 26, 1865. The war was sparked by a dispute over slavery, with the Union opposing its expansion into new territories and the South seeking to preserve and expand the institution. The conflict resulted in the deaths of an estimated 698,000 soldiers and an unknown number of civilians, making it the deadliest military conflict in American history, and led to the abolition of slavery and the collapse of the Confederacy.learn more on wikipedia
